6643.7 kHz AM Freebander Radio Check [Via G8JNJ SDR] 1357 UTC 27 April 2026
« on: April 27, 2026, 1359 UTC »
Somebody doing radio checks, tuning up an antenna or transmitter (in AM mode).  Carrier right on 6643.7 kHz, then slight VFO swish up to 6640 kHz, then 6645 kHz, then 6650 kHz...then back to 6644 kHz and then 6645 kHz. 

It was somebody a mic in AM mode as faint background noise could be heard
